Patented Oct. 27, 1908.

State of Indiana, have invented a Rein orced- Cement Clvert,containing new and useful features and details of construction, of which the following is a full and accurate s ecification and exposition, bein such as enable others to make and use t e same with absolute exactitude.

The objects of my present invention, broadly speaking,is to provide a culvert or the like composedof cementitious material formed upon a reinforcing metal framework thewhole constituting av culvert which be easy to manufacture, having a maximum of strength, being practically indestructible, and which can be made and sold ata comparatively low rice.

A further o ject is to provide a culvert which may be manufactured in any size and be formed in'one or a plurality of sections as desired, .with means for securely connecting the sections together to forma waterproof joint.

Other minor objects and particular advantages will be made apparent in the course of the following specification.

One manner for carrying out my invention in a practical manner and that which in ractice has been found the most desirab e, is shown most clearly in the accompanying drawings, in which,

Figure 1 is a sectional view of a'portion of two sections joined together in operative po- Fig. 2 is an end view of a portion of the reinforcement of one of the sections. And Fig. 3 is a crosssectional view, taken through the body of one of the sections.

Similar indices denote like parts throughout the several views of the drawings.

In yorder thatconstruction of my invention may be more fully understood and its many advantages be fully appreciated, I will now take up a detail description thereof in .whichy I will set forth thelconstruction as briefly and It should` be understood,` when there is more thanone section, that each of the sections are td be formed identical with each other, the vtwo ends of each `section being formed substantially as shown in Fig. 1.l

The parts shown 1n the left-hand section in Fig. 1 will be indicated bycertain numerals,

whilelike parts in the right-hand section will be denoted by similar numerals primed, it being-understood the left-hand end of'the left'- hand section has itsilange or end portion constructed identical with the left-hand end o of the-right-handsection, and vice versa. i The indices 1 and 1 Adenote each a sheet of Vmetal bent into a substantially cylindrical 'shape and provided with spaced circumferential corrugations extending from end-to- 6.-; end thereof, the longitudinal meeting edges of said sheets being overlap edfand riveted, L' or otherwise secured, together as indicated by the rivet a, in Fig. 3. Extending longitudinally of said vsections are a plurality of 7o metal bars 2 and2, each secured to the outer apexes of eachof-the corrugations by rivets 3 and 3 by which the bars are secured to the metal tubing as indicated. vAlso ex tendin longitudinally of the sections, but locate on the inner surface thereof, are a plurality of metal bars 4 and 4, each secured `to the inner apexes of each of the corrugations by the rivets 5 and 5. The bars 4 4 are positioned alternately-with the bars 2-2, 80 fas is indicated in Fig. 3, and they are posi- 4tioned a short distance apart. The ends of the bars 2-2 extend at each end beyond the termini of the metal tube towhich they are secured, from the ends of which they are bent outward and back formi the loops b and c, substantially as shown in ig. 1. And the ends of the/bars 4-4 extend at each end beyond the ymetal tube to which they are secured and are bent back main portionforming the ooks d and e, sub. stantially as shown in Fig. 1. A plurality of apertures are Vformed through the wall of the metal tubes, said apertures being indicated b the letter f, as shown in Fig. 3, and are or the purpose of allowin the cement on eachside of the metal tubeto eunited therethrough.

'After the yIn'etal reinforcing has been formed asshown and described,l the wholeis covered witha com arativel heavy thickness of cement, whic is -mol ed in form desired,'substantially' as 'shown in Figjl, in which the numerals --designate the cement body and the-numerals 7-7 denote 105 the outwardlyextendin and oppositely disposed cement flanges. xtendmg around in the oppositely dis osed faces of the flanges 7-7 1s a channe 8--8, the two channels,

when united, forming anjinclosed aperture, 110

ras' indicated in Fi,.j;1. At onel point in its.

circumference the said aperture. extends out arallel with their 90 l to the periphery of the flanges, forming the pour-hole 9, as indicated in Fig.` 2, thereby forming an inlet to said aperture after two sections have been united, for the purposes formed in the flange to receive the hea`ds,`

Which will prevent the bolts from turning When their nuts are being turned thereon.

Said bolt apertures are located at points between tWo oops b and between two loops c.

Any desired number'of sections may be thus secured together, after which a thin compost of cement may be prepared and poured in the channel 9, filling the channel 8 8 which,

after, the ycompost has solidified, Will unite the sections and form aWater-tight joint.

I desire that it be understood that While I have shown andl described a specific construction I am not limited thereto, but am entitled to a broad construction of the principles here involved, it being understood that various changes may be madein details of construction Without departing from the principles of my inventlon or sacrliiclng any `of the advantages thereof.

Having now. fully shoWn and described my invention, and the best means for its construction to me known at this time, what I f claim and desire to secure by Letters Patent of the United States, is-

1. A culvert or the like com rising a circumferentially corrugated Inetai)tube having a plurality of apertures therethrough, a lura ity of .bars secured to the inside Wal of the tube', a plurality of bars secured to the outside Wall of the tube, the end ortions of the last named bars being curved ack, a cement body coverin all of said metal parts and having a notch ormed in one end thereof right-angles from around each en and a tongue formed at the other end thereof, and a flange formed at each end thereof, two

or more of the sections thus formed-being adapted to be connected tandem.

2. A culvert or the like formed ofcenlent sections, a flange extending out froml around -'each' end of each section, having a notch formed in one end of each section, a tongu'e extending out from the other end of each 'section, means for sealing the adjoining ends of the sections together, which means comprises a half-round channel formedin o positely disposed adjoining faces of each o the flanges which' togetherA form ab substantially round aperture which at one point opens to the peripheryy of the flanges, said aperture being adapted to be filled With a sealin compost after the sections are united, bo ts for.`

connecting the-sections, and means for reinforcin the sections.

3. culvert or the like comprising a corrugated sheet metal ,section formed cylindrical 1n cross section, a plurality of bars located both on the exterior and the interior and extending longitudinally of and secured to said sheet metal, reverse curves formed bythe ends of said bars, and a cement body inclosingl said metal arts, all substantially as shown and descri ed` 4. A culvert or the like formed of tubular i cement-sections, flanges extendin -out at of each section, a notch formed on one end of each section, a tongue extending out froln'the other end of each section, the said tongue of one section being "adapted, todill the notch of the adjoining section, bolts for securingthe flanges of adjoining sections together, means for sealing the adjoining ends of the sections after they are secured together, anda system of reinforcing xinclosed 1n each of lthe sections, substantially as described.

In testimony whereof I have hereunto sub- I scribed my name to this specification in the presence of tWo subscribin Witnesses.
